When life gives you lemons, skip the lemonade and make these easy lemon bars instead. This recipe delivers a press-in shortbread crust topped with a tangy, luscious lemon filling and finished with a light dusting of powdered sugar. Made with simple pantry ingredients and straightforward steps, these bars are quick to prepare and always a crowd-pleaser.
I use citrus in cooking and baking all the time—its bright acidity lifts flavors and brings a burst of freshness to desserts. Lemon desserts are a personal favorite, and while many recipes are worth keeping, these easy lemon bars stand out for their balance of buttery shortbread and vibrant lemon filling.
Why you’ll love this recipe:
- Rich, buttery shortbread crust with a silky, tangy lemon topping.
- Minimal, everyday ingredients and straightforward steps—no special equipment required.
- Flexible: swap lemon for other citrus like lime, key lime, Meyer lemon, orange, or grapefruit to change the flavor profile.
Recipe ingredients
This easy lemon bars recipe uses just six core ingredients. The list below includes the amounts needed for an 8×8-inch pan that yields about 9 bars.
Ingredient notes
- Fresh lemon juice: For the brightest, cleanest flavor, use freshly squeezed lemon juice. Meyer lemons work beautifully if you prefer a slightly sweeter, floral note. Bottled juice lacks the brightness of fresh citrus.
- Powdered sugar: Powdered sugar is used in the crust and as a finishing dusting. Its fine texture (and small amount of cornstarch) helps produce a tender, melt-in-your-mouth shortbread.
- Flour and eggs: All-purpose flour creates structure in both the crust and the filling; eggs provide the custard-like set for the lemon layer.
How to make this recipe
This recipe has two main components: a press-in shortbread crust and a lemon custard filling. Both come together quickly, and assembly is simple.
Pro tip: Juice and strain the lemons ahead of time, then stir the lemon zest into the juice and refrigerate for up to 2–3 days. Lemon juice also freezes well if you want to prepare in advance.
- Preheat the oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper or foil, leaving an overhang for easy removal.
- In a large bowl, beat 1/2 cup (1 stick) softened unsalted butter with 1/4 cup powdered sugar until light and fluffy, about 2–3 minutes. Add 1 cup all-purpose flour and 1/4 teaspoon salt, and mix on low speed until just combined.
- Press the dough evenly into the prepared pan using an offset spatula or the back of a spoon. Bake on the middle rack for 20–25 minutes, until the crust is lightly golden. Remove from the oven and let cool slightly while you prepare the filling.
- In a medium bowl, whisk together 3 large eggs and 1 cup granulated sugar until smooth. Whisk in 3 tablespoons of flour, then whisk in 1/2 cup fresh lemon juice and 1 tablespoon lemon zest until well combined.
- Pour the lemon filling over the cooled crust and return to the oven. Bake 20–25 minutes more, until the filling is set and no longer wobbly when the pan is gently shaken. Avoid overbaking to prevent cracking and a dry texture.
- Cool the pan completely on a wire rack (about 3 hours) before slicing. When fully cooled, dust the top with powdered sugar and cut into squares with a clean, sharp knife, wiping the blade between cuts for neat edges.
FAQs
These lemon bars use a shortbread crust made from butter, powdered sugar, flour, and a pinch of salt, topped with a lemon filling of eggs, granulated sugar, additional flour to thicken, lemon zest, and fresh lemon juice.
How can you tell if your lemon bars are set?
The filling is done when it appears firm and does not wobble when you gently move the pan. A slight jiggle in the center is okay if it finishes firm while cooling, but it should not be loose or liquid.
How do you cut lemon bars cleanly?
Make sure the bars are completely cool, ideally at room temperature for about three hours. Use a very sharp knife and wipe it clean between cuts for tidy squares. Chilling briefly can also help if you prefer firmer slices.
Recipe notes
- This recipe doubles easily for a 9×13-inch pan—bake a bit longer and check for doneness. A glass pan is recommended when doubling for even baking.
- Allow bars to cool completely before dusting with powdered sugar; the sugar can dissolve if the bars are warm.
- Store leftovers in an airtight container in the refrigerator for up to 5 days.
- Swap lemon juice for other citrus juices to vary the flavor: Meyer lemon, lime, key lime, orange, blood orange, or grapefruit all work well.
- Advance prep: juice and strain lemons, then add zest to the juice and refrigerate or freeze until ready to use.
